HOMER W. CASE, PITTSBURG, PENNSYLVANIA, ASSIGNOR TO TRUSS STEEL TIE COMPANY, A CORPORATION OF THE DISTRICT OF CO- LUMBIA.

TIE FOR RAILROADS.

Patented Nov. 6, 1906.

Application filed June 19, 1905. Renewed. October 1.1906. Serial No. 336,998-

To ail whom it may concern.-

I e it known that I, HOMER W. C-Asn, a cltizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Ties for Railroads, of which the following is a specification, reference being had therein to the accompanying drawings.

My present invention relates to improvements in ties for railroads, the main object being the provision of a metal truss-tie, preferab y made of steel, in which the ties are arranged in zigzag order and are provided with a clamping means to secure the rail and tie together and prevent any objection to the free passage of the rollingstock upon the rail.

Another object of my invention is the provision of a means whereby the zigzag order of ties may be dispensed with and the single metal tie, in combination with the new and improved clamping means, as hereinafter set forth, is employed.

In the accompanying drawings, Figure 1 is a perspective vlew of a section of track wit-h my improved truss-tie and clamping mechanism in operable position, a portion of the road not being ballasted. Fig. 2 is I a top plan view of one tie, showing it connected to the rail, the tread of the rail being broken away to show more clearly the construction. Fig. 3 is a cross-sectional view through the tie, showing the clamp mechanism in elevation and a portion of the rail. Fig. 4 is a detail perspective view of a tie and rail equipped with my invention. Fig. 5 is a detail view of the clamp and form of tie used where the ties are not arranged in zigzag order. Fig. 6 is a top plan view of one of the ties, the clamping device, and a rail, the tread of the rail being broken away to clearly show the clamping device.

Referring to the drawings, the numeral 1 designates my metal tie, which is provided,

as inmy former application, with the flanged 'so that the upper sulation 7, which is substantially triangular in cross-section, as clearly shown in Fig. 3. In order to hold the rail securely in pos1- tion in connection with the tie and the insu- I lation therebetween, I provide the two clamping members 8 and 8, each one of which is provided with the flange or hooked end 9, adapted to engage the under surface of the supporting-plate 3 of the tie, the short vertical portion 10 being opposed to the'end of the plate 3 and the block of insulation 6, while the inclined portion 11 engages one of the upper inclined surfaces of. the triangular b ock of insulation 7, the said inclined portion 11 being further provided with the reduced portion 12, having the lower inclined edge 13, adapted to en age that portion of the insulating-block 7 w ich bears upon one flange of the base of the rail, as clearly shown in Fig. 4.

In order to clamp the members securely together, so as to engage properl the supporting-plate 3 of the tie, I emp oy a bolt 14, which passes through the portion 10 ofeach vmember of the clamp and through a channel 15, formed through the bod of the'block 6, the said bolt being secure in position by means of the nut 16. In order to clamp the upper portions of the members together upon the triangular-sha ed block 7, I emplloy the bolt or rod 17, whidii passes through t e opening in the enlarged ortion 18 of the members, the entire en 19 of said rod being threaded, so as to receive the nuts 20 and 21, ortion of the members may be drawn close y together upon the triangular block 7, thus locking the rail securely into close proximity with the tie. These clamps, it will be noticed, are arranged in pairs, one upon each side of the base of the rail, and, as shown in Fig. 1 of the drawings, the ties are arranged in zigzag order, and t e rod or bolt 19 is so constructed as to be of sufiicient length to engage two pairs of the clamping members, thus securing the nearer ends of the ties together and forming a truss case of derailment to slide, and thus not crush the clamping members.

As shown in Fig. 2 of the drawings, the

ties are arranged at an angle to the base of the rail, and the bodies of the clamping members are so arranged that the downwardlyprojecting portion thereof is parallel to the edge of the supporting-plate 3 of the tie,- but, as shown in Fig. 5, where it is desired to dispense with the zigzag arrangement of the ties the supporting-plate of the tie is provided with the pairs of notches 24 and 25 upon the edges near each end of the tie, and the central portion 26 being adapted to receive the base-flange of the rail, while the notched portions 24 and 25 receive the clamp ing portions of the clamp, and thus provide a means whereby the rail is prevented from spreading, as both clamping members are bolted together toward each other and hold the rails upon the portion 26.

order to assist the ties, I arrange in the space between the spread ends thereof an auxiliary plate or support 27, which is adapted to be bolted or secured to the rail at 28 and be sunken in the ballast.

I clearly show in Fig. 1 of the drawings the ties covered by the ballast, so that just the plate 3 thereof is observable, thus pro viding means whereby the noise occasioned by metal ties is dispensed with, thus providing a system of truss steel-tie support for rails which is thoroughly eflicient and practical in use and which is especially adapted for electric railways, as the insulating feature interposed in this construction entirely relieves the objection to metal ties in connection with electric railroads.
